Subtitle maker!

I need a program that I can make subtitles (eg. ssa format) with on a video, with a timeline to refer to. Preferably with an audio extracter so I can just use the audio timeline to sync my subtitles to the video.

I've worked with Subtitle Workshop and Aegisubs on PC. But are there similar programs for Mac, other than Miyu? I don't like Miyu, it's not convenient at all. Miyu does not allow extracting the audio or a timeline to refer to.
